Disconnected quark loop contributions to nucleon observables using $N_f=2$ twisted clover fermions at the physical value of the light quark mass

We compute the disconnected quark loops contributions entering the determination of nucleon observables, by using a $N_f = 2$ ensemble of twisted mass fermions with a clover term at a pion mass $m_π= 133$ MeV. We employ exact deflation and implement all calculations in GPUs, enabling us to achieve large statistics and a good signal.
